Specification of Letters Patent. P te ted July 1'7, 1917. I

Application filed November 24, 1915. Serial No. 63,242.

To all whom it may concern:

Be it known that I, FRANK A. PI-IILLIIPI, a citizen of the UnitedStates, residing in Pottstown, Montgomery county, State of Pennsylvania,have invented certain Improvements in Coolers, of which the following isa specification.

One object of the invention is to provide a compact, substantial, andeasily cleaned cooler for liquids such as water, beer and the like,whose arrangement of parts shall be such as to cause a rapid andeflicient lowering of the temperature of the liquid under treatment.

A further object of the invention is to provide a cooler with novelmeans for causing circulation of the liquid, and which shall be soconstructed as to permit of the con-- venient removal of the liquiddirecting element for purposes of inspection and cleanlng.

These objects and other advantageous ends I secure as hereinafter setforth, reference being had to the accompanying drawings, inwhich, 7

Figure 1 is a side elevation of a cooler constructed according to myinvention;

Fig. 2 is a central vertical section taken through the inlet and outlet;and

Fig. 3 is a horizontal section on the line a-a, Fig. 2.

In the above drawings, 1 represents a flanged base casting to which issweated or otherwise suitably connected a relatively thin cylindricalmetal shell 2, there being a boss 3 integral with said casting andhaving a threaded passage 4 which through a suitable opening in thelower part of the casing 2 communicates with the interior thereof.

Similarly sweated or connected to the opposite or top end of the shell 2is an upwardly flanged metal collar 5 having a boss 6 provided with athreaded passage 7 also communicating with the interior of said shellthrough a suitable opening. The upper end of the shell or casing 2 isclosed by a cover 8 fitting into the flanged endv of the collar 5 andconfining a body of packing material. or gasket 9. This cover isprovided with a series of forked lugs 10 designed to receive the upperends of elongated bolts 11 pivoted or hinged by pins 13 to lugs 12projecting from the base casting 1. The upper ends of these bolts arethreaded for the reception of wing nuts 14: whereby the cover 8 may bedrawn forcibly into engagement with the gasket 9 to seal the end openingof the casing.

Mounted within the casing or shell 2 is a baffle or liquid directingelement 15 in the shape of an elongated, substantially cylindricalstructure preferably made of glass, porcelain, stoneware or othervitreous material, although it obviously may be made of metal or othersubstance unaflected by the liquid passing through the cooler. Thiselement is formed with a series of annular ribs 17 forming annulargrooves or channels 16 and of such an external diameter as to closelyfit against the cylindrical inner surface of the shell 2, to preventpassage of liquid between adjacent grooves or passages.

Each of the ribs 17 is cut away at one point to provide a passage 18between adjacent annular passages, it being noted that the cutawayportions or openings of adjacent ribs are 180 apart.

The upper end of the bafiie or liquid directing element has the form ofa projecting knob 20 of such length that it is engaged by the cover 8when this is drawn into its sealing position by the bolts 11 and wingnuts 14: so that movement of said element within the shell is prevented.

Under conditions of use the cooler as a whole is packed within asuitable heat insulated box and is surrounded by ice or other coolingmedium, the passages 4 and 7 of its two bosses being connected byconduits to a source of liquid to be cooled and to a receiver for cooledliquid respectively. Any liquid entering the inlet 4, for example,passes therefrom through the adjacent groove 16 until on reaching thelongitudinal passage 18, it flows into the next upper annular channel inwhich it divides into two currents flowing in opposite directions aroundthe element 15. -These two bodies of liquid after each passing half-wayaround the baflie element, unite and flow through the next higherlongitudinal passage into the adjacent annular channel, and so on untilthey finally reach the annular cavity surrounding the kno lp 20 passingfrom thence into the outlet In thus circulating through the variouschannels defined by the grooves in the bafile element 15 and the innersurface of the shell 2, the liquid under treatment is brought intocontact with a considerable area of said inner surface, which ismaintained at a low temperature bythe cooling medium outside the same sothat when such liquid is finally delivered from the outlet itstemperature has been reduced to an extent depending among other thingsupon the number and dimensions of the channels 16 as Well as upon thedimensions of the casing 2.

When desired, the cover 8 may be removed by backing off the Wing nuts 14and there after swinging outwardly the bolts 11 sufliciently to causethem to disengage the forked lugs 10; The baflie element 15 may then beremoved by means of its knob 20, Which is preferably formed tofacilitate its being grasped.

copies of this patent may be obtained for I claim The combination in acooler of a substantially cylindrical casing having an inlet and anoutlet; a liquid deflecting element in said casing consisting of asubstantially cylindrical member having a projecting knob at one end andformed with a series of circular ribs forming substantially liquid tightjoints with the interior surface of the casing, each of said ribs havingan opening to permit of communication between the channels formed by theribs; a cover for the casing engaging the knob of the deflecting elementto hold the latter from movement; and means for normally holding thecover in position.
